The PC strand is mainly used as auxiliary reinforcing strand for concrete structure, such as long spanned bridge's on railway and highway, overhead crane construction, geotechnical anchor construction, multi-floor industrial building and etc.

We can manufacture the PC strand conforming to the technical standards, such as GB/T5223-2002, GB/T5224-2003 of China, ASTM A416 of USA, BS5896:80 of Britain, JIS G3536-88 of Japan, or the standards agreed by both the customers and our company.
